The authors introduced several supporting structures of tube bundles of tube-shell heat exchangers, especially the new self-support structure.
介绍了管壳式换热器几种管束支承结构的研究进展,并着重介绍了一种新型的管子自支承结构。
After comparing with the experiment on bundles of plain tubes,this thesis gained the regression correlative equation concerning the friction resistance coefficient of shell side and heat transfer film coefficient of self-support heat exchanger of pin-finned tubes.
对钉头管自支承式换热器钉头纵向间距分别为20,35和50mm的三种钉头管-光管混合管束进行了壳程性能试验研究,并与纯光管管束试验进行了比较,得到了钉头管自支承式换热器的壳程摩擦阻力系数和传热膜系数的回归关联式。
